    At first we have:
    c: 0s-1s
    new -> a: 1s-1.5s
    new -> b: 1s-2s
    new -> c: 0s-1s [end: 2s]

    Then we remove dur on c giving us:
    c: 0s-2s
    change -> a: 2s-2.5s
    change -> b: 2s-3s
    change -> c: 0s-3s
    change -> a: 3s-3.5s [Should break the cycle here]
    change -> b: 3s-4s
    change -> c: 0s-4s
    etc. 

    If we break on the second change notice we should arrive at:
    a: 2s-2.5s
    b: 2s-3s
    c: 0s-3s
